I've had a few questions about hexagons recently and I keep meaning to post a little hexagon information, so here it is. Finally.
For the hexagons I'm doing, I use the 1 1/2" hexagon cardstock pieces. (The 1 1/2" measurement is the length of each of the six sides. That's where that number comes from.) I bought my pieces from www.paperpieces.com. They arrived super fast. I think it cost me $19.00 for 300 ready-to-use pieces. To me, the price was totally worth not having to spend the time cutting them out myself. And I like that the cardstock gives a little more shape and stability to the process.
Also, I don't cut out hexagon shaped fabric. I use 3 1/2" squares. Much faster and easier to cut out.
Angela lists some good hexagon tutorials here. The thing that really helped me most (I'm such a visual learner) were these Hexagon Tutorial videos at Texas Freckles. They're really short and gave me the confidence to pick up this new hobby.
Hope that helps answer some of those burning questions and gets you ready to start hexing yourself. (That sounds a little like something from Harry Potter.)
In other fun news, my little magnetic pin dish tutorial was featured over at Tipnut.com yesterday. Fun stuff! Have you visited Tipnut.com? Oh my - it's one of my favorite sites for helpful information (tips, if you will) on a myriad of topics. Great links to craft patterns, recipes, gardening, household, downloads, etc. I love it - it's one of my go-to sites!
